If you dwell on death, drowning, and failure, you're setting yourself up for it. Ferrying airplanes is done very day, east and west. Ferrying an airplane is a professional act, not a moment or heroic endevor, not a sign of lack of intelligence, not a rash act. It's a job. Like any job, it requires forethought, planning, and attention to detail. It's not rocket science.
It's not a matter of large testicles, nor of willpower, or guts. It's about planning ahead, and preparing, and then doing. Listening to some of these comments is reminiscent of the fear of the "sound barrier", or so many other mythical imagined realms of flying. It's just a flight. Make it once with someone who has the experience, and then start making the trips on your own.
There's very little long distance ferry movement of airplanes, right now. Comparitively, the business is dead.
